DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-7, 11-18, 22-23 rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because there are three steps claimed in the independent claims. The first two steps are receiving steps where a signal has been received and the third step is a decoding step where the received signal is decoded based on the first two steps. The two receiving steps are paramount to signals per-se as the act of receiving a signal is a passive act based on the physical phenomenon of signals propagating through the atmosphere or another medium and stimulating an antenna or array of antennas resulting in a received signal. The act of decoding a signal transmission based on the received transmission is a purely mathematic operation.
Dependent Claims 2-7, 11-18, and 22-23 fail to overcome the deficiencies listed above and are thus rejected under similar rationale.
Dependent Claims 8-10 and 19-21 are dependent on rejected independent claims 1 and 14 respectively and are therefore objected to as dependent on a rejected independent claim.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 24-30is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lee (US 20250150119 A1) hereafter Lee.

In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 20250150119 A1) hereafter Lee in view of “Outage Performance Analysis of HARQ-Aided Multi-RIS Systems” 2021 IEEE Wireless Communications and Networking Conference (WCNC) 29 March 2021 hereafter IEEE.
Regarding Claim 1:
Lee discloses:
An apparatus for wireless communication, comprising: a memory; and at least one processor coupled to the memory and configured ([¶0175] Referring to FIG. 17, a terminal 1700 may include a transceiver 1710, a controller 1720, and a storage unit 1730. The controller 1710 may be defined as a circuit or an application-specific integrated circuit or at least one processor.) to: receive a first number of repetitions of a signal transmission from a base station; ([¶0071] In the LTE system, scheduling information for DL data or UL data is transmitted in DCI from a base station to a terminal. Several DCI formats are defined and operated by applying the defined DCI formats depending on whether scheduling information is for UL data or DL data, whether DCI is compact DCI with a small size of control information, whether spatial multiplexing using multiple antennas is applied, whether DCI is for power control, and so on. For example, DCI format 1, which is scheduling control information for DL data, is configured to include at least the following control information [¶0076] New data indicator: Indicates an HARQ initial transmission or an HARQ retransmission.) receive a second number of repetitions of the signal transmission transmitted from a reconfigurable intelligent surface device;([¶0177] According to an embodiment, the RIS 605 may reflect, to the terminals 603, 604 located at the shadow area 607, at least one beam directed to the RIS 605 among a plurality of beams of the base station 601 for performing the wireless communication with the terminals) and
Lee does not disclose:

IEEE discloses:

([Part II Section A] discloses channel modeling with signals from both the RIS and the Base station being decoded. [Part II Section B] discloses the use of a HARQ protocol in decoding the transmission data)
Lee and IEEE are analogous as they both pertain to wireless communication. Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Lee to decode the signal as taught by IEEE in order to improve coverage within the mmWave and terahertz bands ([¶0005] Lee).
Regarding Claim 2:

Lee discloses:
wherein the at least one processor is further configured to: receive control information including a first value indicating the first number of repetitions of the signal transmission from the base station, and a second value indicating the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device.

Regarding Claim 3:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
wherein the at least one processor is further configured to: receive control information including a repetition pattern indication associated with the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device, wherein the signal transmission is decoded based at least in part on the repetition pattern indication. ([¶0016] In an embodiment, the control information may include at least one of timing information indicating a time point at which the terminal measures the strength of the synchronization signals corresponding to the plurality of beams of the base station for each of the plurality of reflection patterns, indication information indicating each of the plurality of reflection patterns and order information indicating an order in which the plurality of reflection patterns are controlled, information about a transmission period of the synchronization signals corresponding to the plurality of beams, and information indicating a number of times the transmission period of the synchronization signals is repeated for each of the plurality of reflection patterns.)
Regarding Claim 4:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
wherein the repetition pattern indication indicates an interleaved repetition pattern where the first number of repetitions of the signal transmission from the base station are interleaved with the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device. ([¶0016] In an embodiment, the control information may include at least one of timing information indicating a time point at which the terminal measures the strength of the synchronization signals corresponding to the plurality of beams of the base station for each of the plurality of reflection patterns, indication information indicating each of the plurality of reflection patterns and order information indicating an order in which the plurality of reflection patterns are controlled, information about a transmission period of the synchronization signals corresponding to the plurality of beams, and information indicating a number of times the transmission period of the synchronization signals is repeated for each of the plurality of reflection patterns.)
Regarding Claim 5:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
wherein the repetition pattern indication indicates a consecutive repetition pattern where the first number of repetitions of the signal transmission from the base station are scheduled in a first consecutive order, and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device are scheduled in a second consecutive order. ([¶0016] In an embodiment, the control information may include at least one of timing information indicating a time point at which the terminal measures the strength of the synchronization signals corresponding to the plurality of beams of the base station for each of the plurality of reflection patterns, indication information indicating each of the plurality of reflection patterns and order information indicating an order in which the plurality of reflection patterns are controlled, information about a transmission period of the synchronization signals corresponding to the plurality of beams, and information indicating a number of times the transmission period of the synchronization signals is repeated for each of the plurality of reflection patterns.)
Regarding Claim 6:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
wherein the at least one processor is further configured to: process the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device based at least in part on whether the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device are quasi co-located with different downlink reference signals or a same downlink reference signal. ([¶0082] Referring to FIG. 2, the PDCCH 201 is time-multiplexed with a data transmission channel, Physical Downlink Shared CHannel (PDSCH) 202 and transmitted across a total system bandwidth. A region of the PDCCH 201 is represented as the number of OFDM symbols and indicated to a terminal by a Control Format Indicator (CFI) transmitted on a Physical Control Format Indicator CHannel (PCFICH). As the PDCCH 201 is assigned to starting OFDM symbols of a subframe, it has the advantage of allowing the terminal to decode a DL scheduling assignment as soon as possible, thereby reducing the decoding delay of a DownLink Shared CHannel (DL-SCH), that is, an overall DL transmission delay. Since one PDCCH carries one DCI message and multiple terminals may be scheduled simultaneously on DL and UL, multiple PDCCHs may be transmitted simultaneously within each cell. A cell-specific reference signal (CRS) 203 is used as a reference signal (RS) for decoding the PDCCH 201. The CRS 203 is transmitted across the total band in every subframe and subject to different scrambling and resource mapping depending on a cell identity (ID). Since the CRS 203 is an RS common to all terminals, terminal-specific beamforming may not be used. Therefore, a multi-antenna transmission scheme for the PDCCH in LTE is limited to open-loop transmit diversity. The number of ports for the CRS 203 is implicitly known to the terminal from decoding of a Physical Broadcast CHannel (PBCH).)
Regarding Claim 7:
Lee in view of IEEE discloses the limitations of parent claims:

([¶0143] According to another embodiment, the control signal 1001a transmitted from the base station 901 to the RC 904 may include at least one of information about timing at which measurement for obtaining the optimal beam of the base station 901 and the optimal reflection pattern of the RIS 903 for the target shadow area 905, information indicating each of the plurality of reflection patterns of the RIS 903 (e.g., index information indicating a reflection pattern) and information about an order in which the plurality of reflection patterns of the RIS 903 are applied, and information about a time interval which needs to be applied for each of the plurality of reflection patterns of the RIS 903.

([¶0071] In the LTE system, scheduling information for DL data or UL data is transmitted in DCI from a base station to a terminal. Several DCI formats are defined and operated by applying the defined DCI formats depending on whether scheduling information is for UL data or DL data, whether DCI is compact DCI with a small size of control information, whether spatial multiplexing using multiple antennas is applied, whether DCI is for power control, and so on. For example, DCI format 1, which is scheduling control information for DL data, is configured to include at least the following control information. [¶0072] Resource allocation type 0/1 flag: Indicates whether the resource allocation scheme is type 0 or type 1. Type 0 applies a bitmap scheme to allocate resources on a resource block group (RBG) basis. In the LTE system, a basic scheduling unit is a resource block (RB) represented by time and frequency-domain resources, and an RBG includes a plurality of RBs, which is a basic scheduling unit in type 0.

For example, DCI format 1, which is scheduling control information for DL data, is configured to include at least the following control information.

([¶0107] According to an embodiment, in the case of the LTE-A system, the terminal may feed back DL channel state information to the base station so that the base station uses the DL channel state information for DL scheduling. For example, the terminal measures an RS transmitted on DL by the base station and feeds back information extracted from the measurement to the base station in a form defined by the LTE/LTE-A standard.

([¶0071] In the LTE system, scheduling information for DL data or UL data is transmitted in DCI from a base station to a terminal. Several DCI formats are defined and operated by applying the defined DCI formats depending on whether scheduling information is for UL data or DL data, whether DCI is compact DCI with a small size of control information, whether spatial multiplexing using multiple antennas is applied, whether DCI is for power control, and so on.

Regarding Claim 14:
A method of wireless communication for a user equipment (UE), comprising: receiving a first number of repetitions of a signal transmission from a base station; ([¶0071] In the LTE system, scheduling information for DL data or UL data is transmitted in DCI from a base station to a terminal. Several DCI formats are defined and operated by applying the defined DCI formats depending on whether scheduling information is for UL data or DL data, whether DCI is compact DCI with a small size of control information, whether spatial multiplexing using multiple antennas is applied, whether DCI is for power control, and so on.

Lee does not disclose:
decoding the signal transmission based at least in part on the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission transmitted from the reconfigurable intelligent surface device.
IEEE discloses:
decoding the signal transmission based at least in part on the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission transmitted from the reconfigurable intelligent surface device. ([Part II Section A] discloses channel modeling with signals from both the RIS and the Base station being decoded. [Part II Section B] discloses the use of a HARQ protocol in decoding the transmission data)
Lee and IEEE are analogous as they both pertain to wireless communication. Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Lee to decode the signal as taught by IEEE in order to improve coverage within the mmWave and terahertz bands ([¶0005] Lee).
Regarding Claim 15:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
further comprising: receiving control information including a first value indicating the first number of repetitions of the signal transmission from the base station, and a second value indicating the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device. ([¶0016] In an embodiment, the control information may include at least one of timing information indicating a time point at which the terminal measures the strength of the synchronization signals corresponding to the plurality of beams of the base station for each of the plurality of reflection patterns, indication information indicating each of the plurality of reflection patterns and order information indicating an order in which the plurality of reflection patterns are controlled, information about a transmission period of the synchronization signals corresponding to the plurality of beams, and information indicating a number of times the transmission period of the synchronization signals is repeated for each of the plurality of reflection patterns.)
Regarding Claim 16:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
further comprising: receiving control information including a repetition pattern indication associated with the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device, wherein the signal transmission is decoded based at least in part on the repetition pattern indication. ([¶0016] In an embodiment, the control information may include at least one of timing information indicating a time point at which the terminal measures the strength of the synchronization signals corresponding to the plurality of beams of the base station for each of the plurality of reflection patterns, indication information indicating each of the plurality of reflection patterns and order information indicating an order in which the plurality of reflection patterns are controlled, information about a transmission period of the synchronization signals corresponding to the plurality of beams, and information indicating a number of times the transmission period of the synchronization signals is repeated for each of the plurality of reflection patterns.)
Regarding Claim 17:
Lee in view of IEEE discloses the limitations of parent claims:
Lee discloses:
further comprising: processing the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device based at least in part on whether the first number of repetitions of the signal transmission from the base station and the second number of repetitions of the signal transmission from the reconfigurable intelligent surface device are quasi co-located with different downlink reference signals or a same downlink reference signal. ([¶0082] Referring to FIG. 2, the PDCCH 201 is time-multiplexed with a data transmission channel, Physical Downlink Shared CHannel (PDSCH) 202 and transmitted across a total system bandwidth. A region of the PDCCH 201 is represented as the number of OFDM symbols and indicated to a terminal by a Control Format Indicator (CFI) transmitted on a Physical Control Format Indicator CHannel (PCFICH). As the PDCCH 201 is assigned to starting OFDM symbols of a subframe, it has the advantage of allowing the terminal to decode a DL scheduling assignment as soon as possible, thereby reducing the decoding delay of a DownLink Shared CHannel (DL-SCH), that is, an overall DL transmission delay. Since one PDCCH carries one DCI message and multiple terminals may be scheduled simultaneously on DL and UL, multiple PDCCHs may be transmitted simultaneously within each cell. A cell-specific reference signal (CRS) 203 is used as a reference signal (RS) for decoding the PDCCH 201. The CRS 203 is transmitted across the total band in every subframe and subject to different scrambling and resource mapping depending on a cell identity (ID). Since the CRS 203 is an RS common to all terminals, terminal-specific beamforming may not be used. Therefore, a multi-antenna transmission scheme for the PDCCH in LTE is limited to open-loop transmit diversity. The number of ports for the CRS 203 is implicitly known to the terminal from decoding of a Physical Broadcast CHannel (PBCH).)
Regarding Claim 18:
Lee in view of IEEE discloses the limitations of parent claims:

([¶0143] According to another embodiment, the control signal 1001a transmitted from the base station 901 to the RC 904 may include at least one of information about timing at which measurement for obtaining the optimal beam of the base station 901 and the optimal reflection pattern of the RIS 903 for the target shadow area 905, information indicating each of the plurality of reflection patterns of the RIS 903 (e.g., index information indicating a reflection pattern) and information about an order in which the plurality of reflection patterns of the RIS 903 are applied, and information about a time interval which needs to be applied for each of the plurality of reflection patterns of the RIS 903. At this time, if information indicating the reflection pattern is the index information indicating the reflection pattern, an index for the corresponding reflection pattern may be defined as p (1≤p≤P) when the corresponding reflection pattern is, for example, Θ.sub.p in FIG. 6. Further, the information about the time interval which needs to be applied for each of the plurality of reflection patterns of the RIS 903 may be represented in a slot unit, a symbol unit, or an absolute time unit (e.g., s, ms, us, etc.).

([¶0143] According to another embodiment, the control signal 1001a transmitted from the base station 901 to the RC 904 may include at least one of information about timing at which measurement for obtaining the optimal beam of the base station 901 and the optimal reflection pattern of the RIS 903 for the target shadow area 905, information indicating each of the plurality of reflection patterns of the RIS 903 (e.g., index information indicating a reflection pattern) and information about an order in which the plurality of reflection patterns of the RIS 903 are applied, and information about a time interval which needs to be applied for each of the plurality of reflection patterns of the RIS 903.
